Full textAbstract:
The structure of modern employment continues to evolve with substantial growth occurring in contractual tripartite relationships. In this thesis there is an exploration of the contractual (non-employment) tripartite relationship between employment agents, hosts and technical white-collar contractors in Australia's mining, technical, consulting and construction sectors. In this thesis the challenges associated with managing the tripartite relationship are investigated using the theoretical lenses of agency, psychological contract, and power to examine the perspectives of the three groups within the relationship. The findings reveal confusion regarding the roles and incumbent responsibilities of the agents, hosts, and contractors. All three groups are uncertain as to which of them is responsible for the contractor in this complicated three-way relationship. Implications and recommendations for future research and practice changes are noted.

Full textAbstract:
In questa tesi vengono presentati degli studi su un prototipo di rivelatore per un modulo PET con cristallo segmentato, condivisione della luce e lettura della stessa da una singola faccia.
Un apparato sperimentale dedicato è stato inizialmente sviluppato e caratterizzato, per poter soddisfare tutti i requisiti in termini di risoluzione spaziale, temporale ed energetica. Questo setup permette la lettura di molteplici canali con catene parallele per misure di tempo ed energia e numerose possibilità di automazione, date dalle molteplici meccaniche impiegabili. La flessibilità di questo apparato ha permesso di effettuare i successivi studi impiegando gli stessi software di acquisizione e analisi. Inoltre, apre la possibilità di ulteriori test su detector a molti canali e per la ricostruzione di immagini.
La prima applicazione di questo setup è stato il miglioramento della risoluzione temporale di coincidenza di un modulo PET usando l'informazione relativa alla profondità di interazione. Il contributo alla risoluzione temporale dovuto alle differenti velocità di propagazione di fotoni gamma e ottici all'interno del detector è stata mitigata con un algoritmo che richiede solamente una misura di calibrazione rispetto al rivelatore impiegato. Per ottenere la migliore risoluzione temporale possibile in questa configurazione, molteplici marche temporali sono state combinate per ottenere una miglior stima del tempo di interazione. Questo lavoro è particolarmente interessante per una possibile applicazione in macchine PET ad alta risoluzione, in quanto impiega una lettura della luce da un singola faccia e richiede costi di produzione solo leggermente superiori in confronto a moduli esistenti simili sprovvisti di informazione DOI.
Inoltre, è stato sviluppato un algoritmo per identificare correttamente il cristallo di prima interazione nei casi di scattering Compton tra cristalli. Questi sono eventi in cui il fotone gamma primario interagisce con più di un canale della macchina PET. Diversi approcci al problema sono usati in letteratura; uno di questi è l'uso di un algoritmo per riordinare le deposizioni di energia. Questo è l'approccio usato anche in questo studio: è stato sviluppato un nuovo algoritmo, è stato testato con simulazioni Geant4 ed è stato applicato a un modulo PET precedentemente sviluppato usando il setup sperimentale inizialmente sviluppato. La possibilità di includere eventi ICS con una buona accuratezza potrebbe permettere di aumentare la sensitività o la qualità dell'immagine, a seconda di quale metodo è messo a confronto. La possibilità a lungo termine di questo algoritmo sono discusse in conclusione.In this thesis we will present different studies carried out on a prototype of PET module detector with pixelated crystals, light sharing and single side readout. A dedicated experimental setup was initially developed and characterised, in order to satisfy all the requirements in terms of spatial, energy and time resolution. This setup allows multiple channels readout with parallel chains for energy and time measurement and various possibilities for automation given by several possible mechanics arrangement. The flexibility of this setup allowed to perform all the successive studies using the same Data Acquisition electronics and software. Moreover, it opens up the possibilities for further tests on multi-channels detectors and on image reconstruction. The first application of this setup was the improvement of the Coincidence Time Resolution of the PET module exploiting Depth Of Interaction information. The contribution to the time resolution due to different speed of gamma and optical photons inside the detector was mitigated with an algorithm that only requires a calibration measurement compared to the DOI capable prototype used. To achieve the best possible time resolution in this configuration, multiple time stamps were combined to obtain a better time of interaction estimator. This work is particularly interesting for possible application in high resolution PET scanners, because it relies on single side readout and requires production costs only slightly higher compared to a similar existing module without DOI capability. Moreover, an algorithm was developed to correctly identify the crystal of first interaction in case of Inter-Crystal Scatter events. These are events in which the primary gamma photon interacts with multiple channels of the PET detector. Different approaches to the subject are found in literature; one of these is to use an algorithm to sort the energy depositions. This is the approach used in this study: a new algorithm was developed, preliminary tested by means of Geant4 simulations and later applied on the PET module previously developed using the experimental setup originally described. The possibility to include ICS event with good accuracy would allow to increase sensitivity or image quality depending on the method to whom this approach is compared to. The long term possibilities of this algorithm will be discussed further at the end of this thesis.

Kassenova, Togzhan O. "Cooperative security in the post-Cold War international system : the cooperative threat reduction (CTR) process." Thesis, University of Leeds, 2004. http://etheses.whiterose.ac.uk/2656/.
Full textAbstract:
The thesis explores cooperative security efforts between the United States and Russia in the framework of the Cooperative Threat Reduction (CTR) Programme and other non-proliferation programmes, which were established in the aftermath of the Soviet collapse as a response to nuclear proliferation threats in the former Soviet Union. One of the main objectives of CTR is to reduce nuclear dangers associated with vast nuclear arsenals, which first and foremost, means reductions in nuclear weapons. This work presents an overview of different proliferation threats ranging from proliferation of nuclear material to potential “brain-drain” from the former Soviet nuclear complex, explains their technical and socio-economic aspects and assesses the effectiveness of the U.S.-Russian programmes, which deal with these threats. The CTR process has encountered some major obstacles on its way. The research suggests that some important problems in the implementation of CTR programmes are of bureaucratic nature. However, bureaucratic factors are aggravated by the political factors stemming from the fact that the national security policies of the U.S. and Russia are still in part based on concepts and strategies adopted during the Cold War. This is especially evident with regard to the role assigned to nuclear weapons by both countries. Therefore, the CTR process is used as a laboratory study of the U.S.-Russian strategic relations in the post-Cold War era. The study demonstrates that the processes happening in the international security system below the surface and which might not be so obvious at a glance can be absolutely important for the future of the international system. The CTR process represents a mechanism, which can be used to build a new international system, where the role of the nuclear weapons becomes more and more obsolete.

Full textAbstract:
Purpose – The purpose of this study is partly to illustrate how the AES encryption methods ECB and CTR affect the computational speed when using the GPGPU framework Cuda, but also to clarify the advantages and disadvantages between the different AES encryption modes. Method – A preliminary study was conducted to obtain empirical data on the AES encryption modes ECB and CTR. Data from the study has been analyzed and compared to determine the various aspects of the AES encryption modes and to create a basis for determining the advantages and disadvantages between them. The preliminary study has been carried out systematically by finding scientific works by searching databases within the subject. An experiment has been used as a method to be able to extract execution time data for the GPGPU framework Cuda when processing the AES encryption modes. Experiment were chosen as a method to gain control over the variables included in the study and to see how these variables change when they are consciously influenced. Findings – The findings of the preliminary study show that CTR is more secure than the ECB, but also considerably more complex, which can lead to integrity risks when implementation is done incorrectly. In the experiment, computational speeds are produced when the CPU memory sends to the GPU memory, the encryption on the GPU and how long it takes for the GPU memory to send to the CPU memory. This is done for both CTR and ECB in encryption and decryption. The result of the analysis shows that the ECB is faster than CTR in encryption and decryption. The calculation speed is higher with the ECB compared to the CTR. Implications – The experiment shows that CTR is slower than the ECB. But the most amount of time spent in encryption for both modes are the transfers between the CPU memory and the GPU memory. Limitations – The file sizes of the files tested only goes up to about 1 gigabyte which gave small computation times.

Full textAbstract:
Sammanfattning Bakgrund - Dagens processorer börjar närma sig gränsen för hur höga klockfrekvenser de kan köras i. Detta har lett till att processorer har fått fler kärnor för att kunna exekvera flera processer parallellt med flertrådade applikationer. Det finns dock ofta en stor mängd oanvänd beräkningskraft under långa perioder då datorn är igång som ligger i grafikprocessorn, GPU. Då en GPU kan köra tusentals många fler trådar på samma gång än en CPU har ramverk för att göra mer generella beräkningar på GPU utvecklats, dessa kallas för GPGPU-ramverk. Då varje kärna på en GPU inte är lika stark som på en CPU ligger vinsten i att använda algoritmer som går bra att parallellisera. En sådan algoritm är krypteringsalgoritmen AES som är en av de säkraste och vanligaste krypteringsalgoritmerna som används idag. Syfte – Med hjälp av GPU-accelerering kan man kryptera med AES snabbare än med en traditionell CPU-lösning. För att göra GPU-accelereringen så effektiv som möjligt undersöker detta examensarbete vilken AES-metod samt vilket GPGPU-ramverk man bör välja. Metod – För att undersöka vilken/vilka AES-metoder samt vilka GPGPU-ramverk som var lämpliga att använda för denna undersökning gjordes två litteraturstudier. Utifrån data som litteraturstudierna gav genomfördes experiment för att jämföra de valda GPGPU-ramverken med den valda AES-metoden som ansågs vara mest lämpliga. Resultat – Från litteraturstudierna kom det fram att OpenCL och CUDA blir de rekommenderade GPGPU-ramverken och att CTR blir den rekommenderade AES-metoden för AES-kryptering med GPGPU-programmering. Utifrån experimenten som genomförts kunde det konstateras att CUDA är ett effektivare GPGPU-ramverk än OpenCL för AES-CTR på det testade grafikkortet, GTX 560. Implikationer – CUDA är snabbare vid större filer för att OpenCL begränsas mer av dataöverföringshastigheten än CUDA på ett GTX 560. Begränsningar – Experimenten genomfördes endast på ett grafikkort från Nvidia. Eftersom Nvidia inte har något intresse i att optimera för andra GPGPU-ramverk så kunde inte testresultaten från OpenCL verifieras med externa verktyg. Detta p.g.a. att Nvidias verktyg inte längre stödjer debugging eller profiling för OpenCL. Nyckelord – Processorer, GPGPU, AES, CTR, OpenCL, CUDA, GPGPU-ramverkAbstract Background - Processors today are approaching the limit for how high clockfrequences they can run. This has led to that instead of trying to make them run faster they are instead made with multiple cores so they can utilize parallelization by running several threads in parallel. However aside from the CPU there is still the graphics card which has a large amount of unused computing power for long durations of time while the computer is active. While a GPU might not have as quick processors it instead has several thousands of them at the same time than a CPU which have led to the development of GPGPU-frameworks to use that potential parallelization. The profit in this lies in using algorithms and code functions that got high potential parallelization, one of which is the AES encryption algorithm. AES is one of the most widely used encryption algorithms today and also considered to be one of the most secure. Purpose – By using GPGPU-acceleration the encryption speed of AES is higher than by using a traditional CPU approach. To make the GPU-acceleration as effective as possible this study looks into which AES-method and which GPGPU-framework that should be chosen during development. Method – This study makes two literature studies to determine which AES-methods and which GPGPU-frameworks that are viable for GPU-acceleration of AES. Afterwards this study conducts experiments to determine which of these GPGPU-frameworks are the most effective. Findings – The conclusion drawn from the literature study is that the CTR-method among the AES-methods is preferable due to its parallelization potential and high security measures. Among the current GPGPU-frameworks only two frameworks satisfies the criteria determined from the literature study and those are CUDA and OpenCL. From the experiment the conclusion is thereafter drawn that of the two GPGPU-frameworks CUDA is more effective due to the bandwidth limits that OpenCL have compared to CUDA. This conclusion is valid on at least the tested graphics card, GTX 560. Implications – CUDA is faster at larger file sizes than OpenCL due to limited data transfer speed in OpenCL on a GTX 560. Limitations – The experiments were only conducted on one graphics card from Nvidia due to hardware constraints in that CUDA can only be run on Nvidia hardware. Due to this hardware constraint and Nvidia’s lack of support in their tools for debugging and profiling of OpenCL the results from the testing of OpenCL couldn’t be verified using external tools. Keywords – Processor, GPGPU, AES, CTR, OpenCL, CUDA, GPGPU-framework

La maladie de Marek est un lymphome T du poulet causé par l'herpesvirus de la maladie de Marek. Ma thèse a consisté à caractériser la première sous-unité ARN télomérase virale (vTR), que nous avons mise en évidence dans le génome de la souche MDV-RB1B. La télomérase est une ribonucléoprotéine qui assure l'élongation des télomères et qui est détectée dans plus de 85% des cancers humains. Nous avons réalisé une étude comparative de vTR avec la composante aviaire cTR, homologue à 88%. L'étude de l'expression de vTR a fait ressortir que son promoteur pourrait être une combinaison d'un promoteur similaire à celui de cTR et d'un promoteur potentiellement inductible pendant la tumorigenèse. Par ailleurs, nous avons démontré la fonctionnalité du gène vTR qui semble plus efficace que cTR. Par mutagenèse dirigée, nous avons confirmé que le domaine CR1 de vTR correspondait bien au domaine matriciel, que l'intégrité du pseudonoeud était nécessaire pour l'activité télomérase et enfin que la boîte H assurait la localisation nucléolaire de vTR. Au vue de l'implication de la télomérase dans de nombreux cancers, vTR pourrait être un facteur déterminant dans la tumorigenèse viro-induiteThe Marek's disease is a T lymphoma induced by a herpesvirus, the Marek's disease virus. The aim of my phD consisted of the characterization of the first viral RNA telomerase component identified in the very virulent MDV-RB1B strain. The telomerase is a ribonucleoprotein that is involved in telomere lengthening and that is detected at least in 85% of human cancers. In order to characterize vTR, I made a comparative study of this gene with its avian ortholog cTR, which is 88%. Homologous to vTR. We realized an expression study of vTR, which led us to hypothesize that the promoter region of vTR could be a combination of a promoter similar to cTR and a promoter, which could be induced during tumorigenesis. Otherwise, we demonstrated the fonctionnality of vTR, which thus seems to be more efficient than cTR. We also confirmed by a mutagenesis study that the CR1 domain of vTR is the template sequence, that the integrity of the pseudonoeud domain is essential for the telomerase activity and that the H box of vTR permits the nucleolar localisation of vTR in cells. According to the telomerase involvement in cancers, vTR could be considered as a determinant factor in the tumorigenesis induced by MDV

No Brasil, se espera ter até 2014, de acordo com o prazo da Política Nacional de Resíduos Sólidos, todos os lixões erradicados e os resíduos sólidos urbanos gerados depositados em aterros sanitários. Atualmente, os projetos de aterros sanitários dão oportunidade para um nicho de mercado, o da fonte de geração de energia. Um parâmetro de controle da poluição do ar causada pelos aterros sanitários são as chamadas camadas de cobertura. Nesse contexto, é de fundamental importância o estudo de camadas de cobertura de resíduos por ser um importante elemento de projeto para evitar ou minimizar a poluição do ar devido aos gases gerados em aterros sanitários de resíduos sólidos, já que é o elo existente entre o ambiente interno dos resíduos e a atmosfera. A presente pesquisa aborda o comportamento dos gases em relação à camada de cobertura existentes na CTR de Nova Iguaçu e no Lixão remediado de Seropédica. Foram realizados ensaios de Placa de Fluxo, medição de pressão e concentração dos gases no contato solo-resíduo e emissões dos gases pelos drenos, além das análises de solo in situ e em laboratório. Os ensaios foram realizados de outubro a novembro de 2012. Os resultados indicaram uma inexistência de fluxo de gases pela camada de cobertura, que possui 1,10 m de espessura, do lixão de Seropédica, sendo encontrado apenas fluxo nos drenos. Na CTR Nova Iguaçu, foi verificada que praticamente a inexistência de fluxo de gases com o sistema de gás ligado, mesmo possuindo uma camada de cobertura de 0,8 m.In Brazil, according to the timeframe given by the National Policy of Solid Waste, by 2014, every dump will be eradicated and every municipal solid waste generated will be deposited in landfills. Currently, the landfill projects provide an opportunity for the market, which is a source of energy. A parameter of control of the air pollution caused by landfills is called cover layers. In this context, it is important the study of the cover layers to avoid or minimized the air pollution due to gases generated in landfills, which is the link between the solid waste and the atmosphere. This research addresses the behavior of the gases in relation to the cover layers on the CTR Nova Iguaçu and Dump of Seropédica. Six test trials of the Flux chamber, pressure measurement and concentration of gases in the soil-residue contact and emissions of gases through the drains, in addition to in situ soil analysis and laboratory analysis. The tests trials were performed from October, 2012 to November, 2012. The results indicated no gas flow through the cover layer, which has a thickness of 1.10 m, of the dump of Seropédica, where the gas flow was only encountered through the drains. In CTR Nova Iguaçu, the gas flow was almost inexistent, even having a cover layer of thickness of 0.8 m.

Com o avanço da internet, novos tipos de negócios surgiram. Por exemplo, o sistema de anúncios online: produtores de sites e diversos outros conteúdos podem dedicar em uma parte qualquer de sua página um espaço para a impressão de anúncios de diversas lojas em troca de um valor oferecido pelo anunciante. É neste contexto que este trabalho se insere. O objetivo principal é o desenvolvimento de algoritmos que preveem a probabilidade que um dado usuário tem de se interessar e clicar em um anúncio a que está sendo exposto. Este problema é conhecido como predição de CTR (do inglês, \"Click-Through Rate\") ou taxa de conversão. Utiliza-se para isto uma abordagem baseada em regressão logística integrada a técnicas de fatoração de matriz que preveem, através da obtenção de fatores latentes do problema, a probabilidade de conversão para um anúncio impresso em dado site. Além disto, testes considerando uma estratégia dinâmica (em função do tempo) são apresentados indicando que o desempenho previamente obtido pode melhorar ainda mais. De acordo com o conhecimento do autor, esta é a primeira vez que este procedimento é relatado na literatura.With the popularization of the internet, new types of business are emerging. An example is the online marketing system: publishers can dedicate in any given space of theirs websites a place to the printing of banners from different stores in exchange for a fee paid by the advertiser. It\'s in this context that this work takes place. Its main goal will be the development of algorithms that forecasts the probability that a given user will get interested in the ad he or she is seeing and click it. This problem is also known as CTR Prediction Task. To do so, a logistic regression approach is used combined with matrix factorization techniques that predict, through latent factor models, the probability that the click will occur. On top of that, several tests are conducted utilizing a dynamic approach (varying in function of time) revealing that the performance can increase even higher. According to the authors knowledge, this is the first time this test is conducted on the literature of CTR prediction.

Full textAbstract:
Subglottic stenosis (SGS) is a narrowing of the airway in the region of the cricoid cartilage below the vocal folds and above the tracheal rings. Individuals with SGS experience difficulty breathing at rest and during exertion both of which become increasingly difficult with the level of stenosis severity. Some individuals also experience negative voice changes. Individuals whose stenoses significantly impact breathing generally require medical procedures or surgery, either balloon dilation or cricotracheal resection (CTR). CTR has been shown to improve patients' ability to breathe, but it can also result in permanent vocal changes. Alternatively, balloon dilation results in similar breathing improvements but for a relatively short period of time. Many studies have been published on the effectiveness of CTR; however, only a few have examined the effects of CTR on vocal production. The purpose of this study is to quantify the acoustic and auditory-perceptual features of subglottic stenosis and examine possible acoustic and auditory-perceptual changes in voice production following a revised CTR aimed to minimize voice impact in a group of women. A retrospective chart review identified women with idiopathic SGS who received revised CTR at The University of Utah Voice Disorders Center between 2008 and 2014. Presurgical and postsurgical groups included patients with both pre and post recordings (n = 11) as well as patients with only pre (n = 6) or post (n = 9) recordings. Acoustic quantification of voice signal periodicity, as well as cepstral, spectral, and fundamental frequency (F0) analyses were performed. Auditory-perceptual ratings of overall quality and monotonicity were performed. Cross-sectional and pre-post surgery analyses were completed. Aggregate analyses revealed that both pre and posttreatment SGS patients demonstrated voice disorders in the mild to moderate severity range. Pre-post comparisons indicated no significant voice change after surgery. Mean fundamental frequency decreased from 215 Hz (SD = 40 Hz) to 201 Hz (SD = 65 Hz). Voice disorder severity based on the cepstral spectral index of dysphoniaTM for sustained vowels decreased (i.e., improved) from 41 (SD = 41) to 25 (SD = 21) points. Semitone standard deviation (2.2 semitones) was equivalent from pretreatment to posttreatment. Auditory-perceptual ratings demonstrated similar results. These preliminary results indicate that the revised CTR procedure is promising in minimizing adverse voice effects. Future research is needed to determine causative factors for pretreatment voice disorders, as well as to optimize treatments in this population.

La tesi si propone di studiare metodi e tecniche di studio urbano attraverso modelli 3D digitali. Il caso di studio è il borgo di Chiuro, in provincia di Sondrio, particolarmente significativo per le caratteristiche morfologiche del territorio, per la qualità architettonica dei manufatti presenti, per la dimensione unita alla varietà dei temi da affrontare.
La prima fase dello studio ha riguardato la ricerca cartografica e storica, individuando alcuni elementi che saranno fondamentali nella definizione del modello.
Il processo di costruzione del modello a scala urbana ha poi definito una serie di dati metrici riguardanti prima le caratteristiche orografiche del territorio e poi la dotazione infrastrutturale e gli edifici presenti.
L'utilizzo del modello è stato poi sviluppato ponendo particolare attenzione al centro storico e alla sua evoluzione urbanistica e storica.
Il modello ottenuto, rielaborato attraverso successivi "trattamenti" ha permesso la stesura di tavole contenenti viste assonometriche o prospettiche capaci di illustrare le proporzioni tra i volumi, al fine principale di restituire la realtà urbana visualizzandola in modo comprensibile a tutti e capace di unire, in un unico prodotto, le mappe tematiche con le corrispondenti componenti tridimensionali.

Esta pesquisa apresenta uma revisão bibliográfica sobre as emissões de
metano em aterros sanitários, os conceitos de geração de gases em aterros
sanitários, movimentações de gases em aterro, apresenta os métodos de medição
de gases in situ, tipos de cobertura finais para aterros e a oxidação do metano na
camada de cobertura. A pesquisa também tem como objetivo medir as emissões de
gases e avaliar a infiltração das águas pluviais através da camada de cobertura do
aterro sanitário da CTR Nova Iguaçu. As medições foram realizadas nos meses de
julho a novembro de 2010, na camada de cobertura monolítica existente e em outra
construída sobre uma barreira capilar. Sensores para medir temperatura e umidade
foram instalados em profundidade nas duas camadas. Foram realizados ensaios de
placa de fluxo para medir a composição dos gases e o fluxo através dos dois tipos
de camadas, e avaliadas duas situações: com os poços de extração de gás ativos e
desligados. Os sensores indicaram que em período de baixa pluviosidade, a barreira
capilar apresenta uma eficácia superior à camada monolítica, e com a intensificação
das chuvas, as umidades medidas nos dois tipos de camadas aumentam, e na
barreira capilar o gradiente estabelecido entre os sensores diminui, indicando uma
possível tendência à saturação desta barreira capilar. Porém, com a paralisação das
chuvas, recupera e retoma sua condição inicial. Os resultados de medidas dos
gases demostraram a eficiência do sistema de extração de gás quando ativado,
resultando em emissões quase nulas de metano e gás carbônico nos dois tipos de
camadas. No entanto, quando o sistema está desativado, as emissões através da
camada monolítica são cerca de 3 vezes maiores do que através da barreira capilar.This research presents a literature review on methane emissions from landfills, the concepts of landfill gas generation, the landfill internal gas flow, introduces the methods of measurement of gases "in situ", types of final landfill coverage and the methane oxidation in the cover layer. The research also purposes to measure greenhouse gas emissions and to evaluate the infiltration of rainwater through the landfill cover layer of the CTR Nova Iguaçu. Measurements were made in the months from July to November 2010, the existing monolithic cover layer and another built on a capillary barrier. Sensors to measure temperature and humidity were installed in two layers in depth. Plate assays were performed to measure the flow of the gas composition and flow through the two types of layers, and evaluated two situations with the gas extraction wells active and off. The sensors have indicated that in times of low rainfall, the capillary barrier has superior efficacy to the monolithic layer, and with the intensification of rain, the moisture content measured on two types of layers increase, the capillary barrier and the gradient established between sensors decreases, indicating a possible trend to saturation of capillary barrier. However, with the stoppage of rain, recovers and returns to its initial condition. The results of measurements of gases demonstrated the efficiency of extraction of gas when activated, resulting in near zero emissions of methane and carbon dioxide in the two types of layers. However, when the system is off, the emissions through the monolithic layer is about three times larger than through the capillary barrier.

A study of open clinical trial was performed in order to evaluate and compare the topical treatment of oral hairy leukoplakia with podophyllin resin 25% solution and podophyllin resin 25% solution in association with acyclovir 5%. A case-control study was also performed in order to evaluate factors which predispose to this lesion. For this purpose, 111 HIV-infected patients were selected, being 32 with oral hairy leukoplakia and 79 without oral hairy leukoplakia, treated at Orestes Dinizs Treatment Center of Parasitic and Infectious Diseases, in Belo Horizonte/Minas Gerais. The comparison of the performance of both therapeutic modalities used were evaluated from the number of applications needed to the clinical resolution of the oral hairy leukoplakia, from the correlation and association of the lesions size with the number of applications, from the clinical resolution of oral hairy leukoplakia, and from clinical evaluation three months after the end of the treatment. The predisposing factors evaluated were CD4 T lymphocytes count, viral load, plaques, highly active antiretroviral therapy, gender, salivary flow, xerostomia or dry month, oral candidosis, use of fluconazole, use of systemic acyclovir, use of zidovudine, injecting drug use, smoking and alcohol consumption. The results of this study showed that both modalities of treatment were statistically significant as of the number of applications needed to the clinical resolution of the oral hairy leukoplakia and there was no difference as of the recurrence rate within a period of three months after the end of the treatment. The association of podophyllin resin 25% solution in association with acyclovir 5% had a faster action in the decreasing of the oral hairy leukoplakia size when compared to the isolated use of podophyllin resin 25% solution, and promoted clinical resolution of the oral hairy leukoplakia in 100% of the cases, which did not happen in the group treated only with podophyllin resin 25% solution. In the case-control study it was verified a statistically significant association between the presence of oral hairy leukoplakia and viral load, not use of highly active antiretroviral therapy, presence of oral candidosis, previous use of fluconazole and previous use of systemic acyclovir.Realizou-se um estudo de ensaio clínico para avaliar e comparar o tratamento tópico da leucoplasia pilosa bucal, utilizando-se solução alcoólica de podofilina a 25% e solução alcoólica de podofilina a 25% associada ao aciclovir a 5%. Avaliaram-se também, através de um estudo caso-controle, os fatores predisponentes para essa lesão. Selecionaram-se 111 pacientes portadores de HIV/aids, sendo 32 portadores de leucoplasia pilosa bucal e 79 sem essa lesão, atendidos no Centro de Treinamento e Referência em Doenças Infecciosas e Parasitárias Orestes Diniz, em Belo Horizonte/Minas Gerais. A comparação da atuação dessas modalidades terapêuticas realizou-se a partir do número de aplicações necessárias à resolução clínica da leucoplasia pilosa bucal, da correlação e da associação entre tamanho das lesões e número de aplicações, da resolução clínica da leucoplasia pilosa bucal e da avaliação clínica três meses após o término do tratamento. Os fatores predisponentes avaliados foram contagem de linfócitos T CD4, carga viral, plaquetas, terapia antirretroviral altamente efetiva, gênero, fluxo salivar, xerostomia ou sensação de boca seca, candidose bucal, uso prévio de fluconazol, uso prévio de aciclovir sistêmico, uso de zidovudina, uso de droga injetável, tabagismo e etilismo. Os resultados demonstraram que ambas as modalidades de tratamento foram estatisticamente significativas em relação ao número de aplicações necessárias para a resolução clínica da leucoplasia pilosa bucal e não houve diferença quanto ao índice de recorrência no período de três meses após o término do tratamento. A associação da solução alcoólica de podofilina a 25% ao aciclovir a 5% teve uma ação mais rápida na diminuição do tamanho da leucoplasia pilosa bucal, quando comparada ao uso isolado da solução alcoólica de podofilina a 25%, e promoveu a resolução clínica dessa lesão em 100% dos casos. No estudo de caso-controle constatou-se relação, estatisticamente significativa, entre a presença de leucoplasia pilosa bucal e carga viral, não uso da terapia antirretroviral altamente efetiva, presença de candidose bucal, uso prévio de fluconazol e uso prévio de aciclovir sistêmico.

Full textAbstract:
Les réseaux de capteurs sans fil (RCSF) sont devenus un thème porteur aussi bien pour la recherche académique que pour les activités des services de R&D en raison de leur simplicité de déploiement et de leur potentiel applicatif dans des domaines très variés (militaire, environnemental, industriel). Un RCSF est composé d'un ensemble de noeuds devant être opérationnels et autonomes énergétiquement pour de longues périodes. De ce fait ils sont limités en capacité mémoire et de calcul, et contraint à exploiter une faible puissance de transmission, ce qui en limite leur portée et rend leur débit modeste. Le besoin de sécuriser les communications dans un RCSF dépend de la criticité des données échangées pour l'application supportée. La solution doit reposer sur des échanges sûrs, confidentiels et fiables. Pour assurer la sécurisation des échanges, des techniques de cryptographie existent dans la littérature. Conçues à l'origine pour des réseaux informatiques majoritairement câblés, elles se basent généralement sur des algorithmes complexes et gourmands en ressource. Dans le cadre de cette thèse, nous avons proposé, implémenté et évalué une architecture sécurisée et dynamique adaptée aux communications des RCSF. Elle permet de garantir et de maintenir la sécurité des communications durant toute la durée de vie d'un réseau multi-saut. Nous avons utilisé et adapté des algorithmes standards de cryptographie, tels que AES-CTR et la suite d'algorithmes basée sur ECC, qui permettent à notre architecture de résister à la majorité d'attaques. Nous avons quantifié le surcoût en temps de calcul et en occupation mémoire de notre solution. Les résultats d'implémentation de notre proposition sont issus de mesures réelles faites sur une maquette réalisée à partir de cartes TelosB.

Full textAbstract:
Patch clearcutting can be put to effective use for landowners with relatively small stands of timber. This project was designed to determine how clearcut opening size and mid-rotation crop tree release affects the value and volume of sawtimber at the end of rotation. In 1960 patch clearcuts were established in three different diameters, 50ft (.05ac), 150ft (.41ac), and 250ft (1.13ac). Current stand data (2011) was collected to determine trees per acre, basal area, average tree diameter, volume, and value. These data were input into a growth simulator to determine future trees per acre, basal area, average tree diameter, volume, and value with a crop tree release treatment and a control to 2061. The 50ft openings yielded little merchantable volume at mid-rotation and were primarily composed by shade tolerant species. In the 150ft and 250ft openings, there was better species diversity and an increase in sawtimber volume and value. Using openings of 150ft or greater, landowners can regenerate commercially important species and manage their forests to produce valued timber and maintain aesthetics.

Le contexte général de cette étude est la fusion thermonucléaire contrôlée par Confinement Inertiel (FCI) et, plus particulièrement, l'Allumeur Rapide (Fast Ignitor). Dans ce schéma la maîtrise de la génération et du transport des électrons sont vitaux. Cette thèse est une étude expérimentale de la génération et du transport des électrons rapides créés lors de l'interaction d'un laser ultra-intense (>= 10 19 W/cm2) avec une cible solide. Le diagnostic principal utilisé au cours de cette thèse est le rayonnement de transition. Ce rayonnement dépend des propriétés des électrons qui le produisent et donne des informations importantes sur ces électrons: leur énergie, température, géométrie de propagation, etc. L'analyse spectrale, spatiale et temporelle de ce rayonnement a permis de mettre en évidence l'accélération de paquets périodiques d'électrons qui dans ce cas émettent un rayonnement de transition cohérent (CTR - Coherent Transition Radiation). Nous avons développé des modèles théoriques au cours de cette thèse pour expliquer les résultats expérimentaux. On trouve ainsi deux types de paquets d'électrons émis périodiquement à la fréquence du laser (w0) et au double de la fréquence laser (2w0), mettant en jeu différents mécanismes d'accélération: vacuum heating/absorption résonnante et vxB respectivement. Ces paquets sont également observés par des simulations PIC. La température de ces électrons est de ~ 2 MeV dans nos conditions expérimentales. Ils sont émis à partir d'un point source qui est la tache focale du laser et se propagent de façon balistique; ils peuvent, dans certains cas, être réinjectés dans la cible par un phénomène de re-circulation. Cependant ce diagnostic n'est sensible qu'aux électrons cohérents et relativistes, ce qui explique la faible partie d'énergie totale qu'ils emportent (~ quelques mJ). Le CTR de ces électrons supra-thermiques domine largement le rayonnement émis par les électrons moins énergétiques qui emportent la majorité de l'énergieThe general context of this study is the Inertial Confinement for thermonuclear controlled fusion and, more precisely, the Fast Igniter (FI). In this context the knowledge of the generation and transport of fast electrons is crucial. This thesis is an experimental study of the generation and transport of fast electrons in the interaction of a high intensity laser (≥ 1019 W/cm2) with a solid target. The main diagnostic used here is the transition radiation. This radiation depends on the electrons which produce it and thus it gives important information on the electrons: energy, temperature, propagation geometry, etc. The spectral, temporal and spatial analysis permitted to put in evidence the acceleration of periodic electron bunches which, in this case, emit a Coherent Transition Radiation (CTR). During this thesis we have developed some theoretical models in order to explain the experimental results. We find this way two kinds of electron bunches, emitted either at the laser frequency (ω0), either at the double of this frequency (2ω0), involving several acceleration mechanisms: vacuum heating / resonance absorption and vxB, respectively. These bunches are also observed in the PIC simulations. The electron temperature is of about 2 MeV in our experimental conditions. The electrons are emitted starting from a point source (which is the laser focal spot) and then propagate in a ballistic way through the target. In some cases they can be re-injected in the target by the electrostatic field from the target edges. This diagnostic is only sensitive to the coherent relativistic electrons, which explains the weak total energy that they contain (∼few mJ). The CTR signal emitted by those fast electrons is largely dominating the signal emitted by the less energetic electrons, even if they contain the major part of the energy (∼ 1 J)

Full textAbstract:
Les produits de contraste ultrasonore constituent un véritable apport pour l'imagerie échographique et sont aujourd'hui utilisés en clinique pour l'évaluation de la perfusion cardiaque ou encore la détection de tumeurs. Depuis quelques années, les transducteurs capacitifs micro-usinés (cMUTs) se présentent comme une alternative intéressante aux transducteurs piézoélectriques classiques et offrent certains avantages comme une large bande passante. Nous proposons dans cette thèse d'évaluer le potentiel de cette technologie pour l'imagerie de contraste. Dans un premier temps, notre étude s'est orientée vers l'adaptation des cMUTs à l'imagerie non linéaire. Ensuite, de nouvelles méthodes de détection de contraste, basées sur le comportement spécifique des microbulles, ont été développées pour exploiter les avantages de la technologie cMUT. Comparés aux méthodes conventionnelles, les résultats obtenus montrent une meilleure visualisation des agents de contraste par rapport aux tissus environnants. L'utilisation de cMUTs améliore l'efficacité de ces méthodes démontrant, ainsi, leur intérêt pour l'imagerie de contraste.

Full textAbstract:
Sammanfattning Syfte: Syftet med denna studie är att undersöka om det skett en förändring i mängden redovisning av socialt och miljömässigt ansvarstagande, dvs. hållbarhetsredovisning, i årsredovisningar hos svenska börsnoterade bolag samt undersöka faktorer som kan förklara hållbarhetsredovisning. Metod: Studien har utgått från den positivistiska forskningsfilosofin och använder en deduktiv ansats. För att besvara studiens syfte har en kvantitativ metod använts genom en innehållsanalys samt hypotesprövningar. Populationen består av 142 företag 2012 samt 160 företag 2015 samtliga noterade på Nasdaq OMX Stockholm. Totalt undersöktes 302 årsredovisningar. De data som samlats in är sekundärdata och består av information från årsredovisningar, databaser samt böcker som sedan ställts mot tidigare forskning och teorier. Resultat och slutsats: Studiens resultat visar att det har skett en förändring av socialt och miljömässigt ansvarstagande i företags årsredovisningar. Vårt resultat visar att en positiv förändring av hållbarhetsredovisningen går att utläsa. Dock är denna liten. Studiens statistiska tester visar att det finns ett positivt signifikant samband mellan mängden hållbarhetsredovisning och företags storlek, lönsamhet samt år. Dessutom visar studien att företags bransch har en inverkan på redovisningen men enbart några är signifikanta. Ägarstruktur och kvinnor i styrelsen visar inget signifikant resultat med redovisningen. Uppsatsens bidrag: Studiens praktiska bidrag har kartlagt om det skett en förändring av hållbarhetsrapportering i årsredovisningen hos svenska börsnoterade bolag. Studien påvisar att en positiv förändring har skett mellan 2012 och 2015. Detta kan vara av intresse för de företag som hållbarhetsredovisar. Det teoretiska bidrag denna studie har är att den bidrar med vidare forskning kring variabler som påverkar mängden hållbarhetsredovisning, där lönsamhet och företagsstorlek har en inverkan på hållbarhetsredovisningen. Förslag till fortsatt forskning: Förslag till vidare forskning är att ha ett större spann mellan åren för att tydligare kunna utläsa en förändring. Ytterligare ett förslag är att undersöka rapporteringen på företags separata hållbarhetsrapporter. Till sist ges förslaget om att göra en liknande studie när den nya lagen gällande hållbarhetsredovisning trätt i kraft och blir synlig inom rapporter.Abstract Aim: The purpose of this study is to examine whether there has been a change in the reporting of social and environmental disclosures, i.e. sustainability reporting, in annual reports of listed swedish corporations and to examine factors that can explain the sustainability report. Method: The study is based on positivist research philosophy and uses a deductive approach. In order to achieve the aim of the study a quantitative method has been used through a content analysis and hypothesis tests. The population consist of 142 companies 2012 and 160 companies 2015, all listed on Nasdaq OMX Stockholm. In total 302 annual reports were examined. The data that has been used are secondary data and the information from annual reports, databases as well as books was then set against previous research and theories. Results and conclusion: The result of the study shows that it has been a change in the reporting of social and environmental reporting in annual reports. Our results indicate that a positive change of sustainability reporting can be seen. However the difference is relatively small. The study’s statistical tests indicate that there is a positive significant correlation between sustainability reporting and company size, profitability and time. In addition the study shows that business sector has an impact on the sustainability reporting but only a few are significant. Ownership structure and women in the board shows no significant results with the sustainability report. Contributions of the thesis: This study's practical contribution is to chart if there has been a change over time of this reporting in the annual reports of swedish listed corporations. The study shows that there has been a change between 2012 and 2015. This result can be of interest for corporations that uses sustaniability reporting. The theoretical contribution of this study is that it contributes with further research on variables that affect the production of sustainability reporting. Where profitability and company size have an impact on this accounting method. Suggestions for further research: Suggestions for future research is to have a wider range between the years in order to be able to read a more accurate difference. Another suggestion is to investigate the reporting on companies separate sustainability reports. A further proposal is to do a similar study when the new law enters into force regarding sustainability reporting and becomes visible within the reports.

Previous issue date: 2010-01-12This study aimed to investigate the use of cane sugar ashes from small-scale stills of Eun?polis region, state of Bahia, in pottery mass that can be developed as porcelain stoneware. Bahia is the second largest producer of rum distillery in Brazil. In the production of rum is produced residue called bagasse, which is used to generate electricity in Power plants and in the distillery itself, generating ashes as residue, which is played in nature, causing environmental damage. We studied 5 (five) formulations of 0% 10% 20%, 30% and 40% by weight of the ash, without ignition and 3 (three) formulations of 10%, 20% and 30% with gray ash temperature of 1250?C. The formulation at 0% by weight of ash was used for a comparison between the traditional mass of porcelain stoneware and the masses with the addition of ash calcined, replacing feldspar. The percentage by weight of kaolin and of Clay was kept the same, 30%, and all raw materials were derived from the state of Bahia. The samples were made in uniaxial array with dimensions of (60 x 20 x 5) mm and compressed to a pressure of 45 MPa. Assays were performed to characterize the raw by X-ray fluorescence, X-ray diffraction, ATD and ATG and Dilatometric analysis. The samples were sintered at temperatures of 1100?C, 1150?C, 1200?C and 1250?C, for the specimens with the ashes without ash and 1150? C and 1200? C for specimens with the gray level of calcined 60 minutes. and then we made a cooling ramp with the same rate of warming until reach ambient temperature. The sintered bodies were characterized by water absorption, porosity, linear shrinkage, bending strength and XRD of the fracture surface and the results analyzed. It was proven, after results of tests performed, that it is possible to use the ash residue of sugar cane bagasse on ceramic coating with the addition of up to 10% wt of the residue ash

INTRODUZIONE
Il carcinoma colon-rettale è una delle neoplasie maggiormente diffuse nei Paesi industrializzati .
Rappresenta la seconda causa di morte per tumore nel mondo nei due sessi. L’incidenza mondiale è di un milione di nuovi casi/anno.
In Italia l’incidenza di questa neoplasia è di circa 30-53 nuovi casi/anno/100.000 Tenendo conto che nel 70% dei casi il carcinoma si sviluppa da un polipo adenomatoso degenerato, secondo i dati dell’American Cancer Society il 90% dei carcinomi del colon retto sarebbe prevenibile con un adeguato screening. Tra le metodiche di diagnostica per immagini la colografia-TC (CTC) è attualmente l’indagine di riferimento nello screening e nella diagnosi precoce del carcinoma del colon retto come ampiamente riconosciuto alla letteratura scientifica in ragione della sua non invasività e dell’elevata accuratezza diagnostica.
La colonscopia virtuale è una tecnica di studio radiologica realizzata con una TC a bassa dose di radiazioni ionizzanti in duplice acquisizione prono e supino previo adeguata preparazione intestinale e distensione gassosa del colon .Mediante l’analisi delle immagini su una su una workstation dedicata è possibile di ricostruire il colon in 3D ed eseguirne una endoscopia virtuale.

Da Gennaio 2014 a Dicembre 2016 presso il “Centro Radiologico Potito” abbiamo eseguito 807 indagini di colografia TC. In particolare abbiamo studiato 443 femmine (54.9%) e 364 maschi (45.1%). L’età media è risultata di 59.7 anni.
Abbiamo raccolto le principali motivazioni che hanno condotto i pazienti alla nostra osservazione. La maggior parte degli esami sono stati eseguiti per dolore addominale (260), screening (155) e alterazioni dell’alvo (112). Tra le rimanenti motivazioni la presenza di sangue vivo nelle feci, una precedente colonscopia tradizionale non condotta a termine, stipsi e rettorragia.
RISULTATI
Tutti gli 807 pazienti hanno condotto l’indagine a termine in assenza di reazioni avverse o episodi di discomfort significativi. Nell’ambito delle patologie neoplastiche abbiamo identificato: 12 carcinomi,58 lesioni polipoidi,2 neoplasie di diversa natura (GIST e altro in attesa di istologico).
Tra i pazienti portatori di patologia neoplastica l’età media è risultata 65.7 anni.
Nel nostro lavoro sono emersi inoltre reperti extra colici in 106/807 pazienti. In particolare 34/807 avevano reperti E4 ovvero reperti che hanno potenziale impatto clinico importante ( aneurismi aortici, masse solide parenchimali…)
DISCUSSIONE
Gli attuali programmi di screening non risultano efficaci dato che è stata riscontrata una bassissima adesione (non superiore al 25-40%). Il motivo di questa bassa compliance dei pazienti è da ricercare probabilmente nel discomfort che caratterizza metodiche come la colonscopia ottica sia in rapporto alla sua invasività sia in relazione alla preparazione catartica preventiva di cui essa necessita.
La difficoltà nell’identificare test preliminari efficaci si riscontra nella variabilità estrema dei sintomi che hanno condotto i pazienti positivi per patologia neoplastica all’ indagine. Molto interessante risulta inoltre lo scarso interesse verso l’indagine preliminare più vantaggiosa dal punto di vista costo beneficio ovvero il SOF test :41/72pazienti non hanno eseguito il test.
La CTC si inserisce quindi nella problematica dello screening nel tentativo di incrementare l’adesione dei soggetti asintomatici o con sintomi aspecifici ai percorsi di prevenzione.
CONCLUSIONE
In generale la CTC è ormai ritenuta l’esame radiologico di prima scelta nello studio delle lesioni polipoidi coliche sostituendo completamente il clisma opaco a doppio contrasto come alternativa alla colonscopia a fibre ottiche nei casi in cui questa indagine sia controindicata o impraticabile o non sia stata condotta a termine.INTRODUCTION The colorectal cancer (CRC) is one of the most common cancers in industrialized countries. It is the second leading cause of cancer death worldwide in both sexes. The global incidence of one million new cases / year. In Italy the incidence CRC is approximately 30-53 new cases / year / 100,000. Since the cancer develops from an adenomatous polyp degenereted in 70% of cases , the American Cancer Society has estimated that 90% of colorectal cancers would be preventable with the correct screening protocols. Among the imaging techinque CT-Colonography (CTC) is currently the best tool for screening and early detection of colorectal cancer as widely recognized in the scientific literature due to its non-invasiveness and high diagnostic accuracy. CT colonography is a radiological technique based on a low-dose ionizing radiation CT in two acquisition, prone and supine,after adequate bowel preparation and gaseous distension of the colon Images are analyzed on a dedicated workstation and so It's possible to reconstruct the colon in 3D or to make a virtual endoscopy. METHODS From January 2014 to December 2016 at "Centro Radiological Potito" we performed 807 of CT colonography In particular, we studied 443 females (54.9%) and 364 males (45.1%). The average age was of 59.7 years. We collected the main reasons that led the patients under our observation. Most of the tests were performed for abdominal pain (260), screening (155) and Usual bowel habits (112) Other reasons were the presence of blood in the stool, a suspended previous traditional colonoscopy, constipation and rectal bleeding RESULTS All of our patients conducted CT colonography in the absence of adverse reactions or significant discomfort Among neoplastic diseases, we identified 12 carcinomas, 58 polypoid lesions, 2 other tumors (1 GIST and 1 waiting for histology tests) Among the patients with neoplastic disease, the average age was 65.7 years In our experience we found extra colonic findings in 106/807 patients In particular 34/807 of these patients had E4 findings with an important potential clinical impact (aortic aneurysms, solid parenchymal lesions...) DISCUSSION The current screening programs are not effective: in fact there was a very low adhesion (not more than 25-40%). The reason for this low compliance of patients is probably to be found in the discomfort that characterizes techinque, such as optical colonoscopy in relation to its invasiveness a wellas in relation to the preparation prior cathartic which is needed The difficulty of identifying effective preliminary tests lies in the extreme variability of the symptoms and signs that brought the patients positive for malignancy to undergo CTC Very interesting is also the lack of interest towards FOBT the most advantageous preliminary test from the cost /benefit point of view: 41 / 72 patients didn’t run the test. The goal of CTC is to increase the adhesion of asymptomatic or nonspecific symptoms patients to prevention paths. CONCLUSION In general, the CTC is now considered the radiological best tool in the study of polypoid lesions replacing totally the double contrast barium enema as an alternative to optical colonoscopy when this examination is contraindicated or impractical or has not been completely conducted.

Full textAbstract:
Introduction: Breast cancer is the most frequently diagnosed cancer found in women across the world, with an estimated 2.3 million new cases occurring in 2020. Additionally, over 684,000 deaths annually are attributed to breast cancer across the globe, making it the most common cause of cancer-related death in women. Further, treatment of breast cancer relies heavily on whether or not the cancer cells express estrogen, progesterone, and HER 2 receptors and this expression profile is often related to how quickly the cells grow and spread. In the United States, breast cancer cells that are hormone receptor positive and HER-2 negative make up about 73% of breast cancer cases, and cells that do not express any receptor and are known as triple negative, make up around 12% of cases (American Cancer Society, 2019). With that being said, CT1 and CT3 are novel compounds that have a cytotoxic effect on cell lines representing up to 85% of all breast cancer subtypes in the United States.
Methods: The leaves of Chromolaena tacotana that contains the flavonoids CT1 and CT3 were dried and placed in a soxhlet extractor using dichloromethane (CH2Cl2) to extract the chlorophyll. The flavonoids were extracted using a column chromatography eluted with trichloromethane (CHCl3), a 1:1 dilution of CHCl3:methanol and methanol, followed by isolation and purification of the compounds. Human breast cancer cell lines MCF7, MDA-MB-231, and SKBr3 were treated with CT1 and CT3 at concentrations of 5, 10, 20, 40 and 80 µM, followed by incubation for 24 hours. To assess cell viability an MTT assay was conducted by adding a 5-diphenyl-tetrazolium bromide reagent. The purple-colored formazan crystals were solubilized with acidified isopropanol, then analyzed by spectrophotometry.
Results: CT1 appeared to have the most cytotoxic effects compared to CT3 on MCF7. The opposite effect was observed for SKBr3 with CT3 showing the most effects as compared to CT1. No differential effect was observed on MDA-MB-231 since both CT1 and CT3 showed similar inhibition of cell viability.
Conclusions: The results from the different breast cancer cell lines SKBr3, MCF7, and MDA-MB-231 vary based on how they responded to CT1 and CT3. CT3 was more effective on SKBr3 than CT1. CT1 was more effective on MCF7 than CT3. For MDA-MB-231, both CT1 and CT3 showed similar significant cytotoxic effects. The antiproliferative effects of CT1 and CT3 appear to be concentration dependent on all cells studied. In view of the results from MDA-MB-231 triple negative breast cancer cell line, the cytotoxic effect of the flavonoids is not dependent on the presence of estrogen, progesterone, or HER2 receptors on breast cancer cells. Further studies on the mechanism of action are necessary to elucidate the molecular targets of CT1 and CT3.

Dissertação de Mestrado Integrado em Arquitetura, com a especialização em Interiores e Reabilitação do Edificado apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Mestre.presente Projeto Final de Mestrado tem como objetivo a proposta arquitetónica de um equipamento de saúde, através da aplicação dos conceitos da Luz, da Cor e da Matéria, que se revelam como os principais métodos e ferramentas, para o desenvolvimento e conceção desta proposta que se situa na freguesia de Marvila, em Lisboa. Situada na zona oriental da cidade de Lisboa, Marvila revela um passado com imensos marcos históricos e com um cariz industrial que ainda permanece. Esta zona encontra-se fragmentada e descaracterizada por consequência da desativação industrial e, por essa razão existem diversos problemas que necessitam de ser resolvidos. Ainda assim evidencia diversos pontos de interesse com imensos benefícios, e por meio da sua requalificação urbana, Marvila retorna a integrar-se na cidade de Lisboa. Com a inserção do Equipamento de Saúde, que tem como objetivo servir a população residente e não residente, irá conceder-se uma nova vida ao local, com a promoção e o rejuvenescimento de Marvila. Irá então atrair novas pessoas à freguesia, impulsionando uma diversidade, como a integração, uma interação e convivência social, que outrora existia em Marvila. O Projeto Final de Mestrado encontra-se estruturado por duas componentes de trabalho, sendo a primeira componente a teórica e a segunda componente a prática. Na componente teórica não só foram desenvolvidos os conceitos de Luz, Cor e Matéria, como também o de Arquitetura para Espaços de Saúde. Esses conceitos revelaram-se cruciais para adquirir os conhecimentos sobre estes temas, de maneira a que no processo de elaboração do projeto este se apresente como funcional, lógico e concebível. Relativamente à componente prática, foram exercidos diversos estudos de vários espaços de saúde, seguindo todo o desenvolvimento do equipamento de saúde e quais as soluções ideais, bem como quais as estratégias de luz, cor e matéria que foram implementadas, chegando-se assim à melhor solução de projeto. De seguida, foi realizada uma análise e investigação sobre a freguesia de Marvila, finalizando-se com uma descrição sobre o projeto e todo o processo de trabalho para a conceção do mesmo.
ABSTRACT: This Master’s Final Project has as purpose an architectural proposal of a health equipment through application of the concepts Light, Colour and Matter that turns out to be the main methods and tools for the development and conception of this proposal which is located in the parish of Marvila, in Lisbon. Situated in the eastern area of the city of Lisbon, Marvila has a past filled with great historical landmarks and it still has industrial features. This area is divided and uncharacterized as a consequence of the industrial deactivation and for that reason there are several problems that need to be solved. Even so, it still shows several points of interest with a lot of benefits, and through its urban requalification Marvila returns to be integrated in the city of Lisbon. With the implementation of a health care equipment, which is intended to serve the resident and non-resident population, it will represent a fresh life to the parish with the promotion and rejuvenation of Marvila. It will also attract new people to the place, creating a new diversity as integration, interaction and social living, aspects that used to exist in Marvila. The Final Master Project is structured in two components. The first one is the theoretical component and the second one represents the practical component. In the theoretical component, not only were the concepts of Light, Colour and Matter developed, but also those of Architecture for Health Spaces. These concepts proved to be crucial for acquiring knowledge about these themes, so that in the process of designing the project this is presented as functional, logical and conceivable. Regarding the practical component, were studied several cases of different health care facilities, following the development of the health equipment and the ideal solutions, as well which strategies of Light, Colour and Matter that were implemented, achieving through that way the best project solution. The following step was the execution of an analysis and a research about the parish of Marvila, ending with a description about the project and all the work process for the conception of the same.

The highly active antiretroviral therapy (HAART) improves substantially the prognosis of HIV infected patients. Finding a better regimen for the first antiretroviral treatment is one of the strategies used to improve time and quality of life of people living with HIV/AIDS. A total of 891 HIV infected patients assisted at the CTR-DIP Orestes Diniz and treated with first
antiretroviral therapy with at least three drugs initiated between 1996 and 2007, were evaluated through a longitudinal historical cohort. The patients were followed for 24 months or until interruption, abandon, changing of the regimen or death. The patients were predominantly males, white, young, single and with a low level of education. The PI regimens represented 61.5% of the prescriptions. A progressive decrease in the regimens composed with PI in the first antiretroviral
treatment was observed, in agreement with the modifications recommended by the country committee. At the end of 6 months 69% of the patients were still being treated with the first regimen, 54% at 12 months, 48% at 18 months and 39% at 24 months. The combination of AZT- 3TC-EFV was the regimen most prescribed and lesser failure. The regimens composed with NNRTI showed high efficacy and durability compared to the regimens with PI. The high frequency of regimens, well known for their less tolerability and efficacy, might be responsible
for the worse results of the regimens composed with PI. The CD4 lymphocyte count < 200cells/ mm3, the irregular dispensation of medication and working as housekeeper were risks factors for
failure or interruption of the treatment in the multivariate analyses. The small number of patients with viral load before the beginning of the HAART impaired the correlation with the treatment duration. The intolerance/adverse effects were mainly responsible for failure of the regimen, followed by the abandon/non-adherence and by the virologic failure. When comparing drugs classes, the results showed a significant difference between the causes of interruption of the first HAART with the major percentage of intolerance/adverse effects of patients treated with PI
regimens and therapeutic immunologic failure with patients treated with NNRTI. The regimens composed with EFV showed high durability and efficacy compared to the regimens contained NVP. The patients which antiretroviral regimen were interrupted or failed in the first 24 months,
showed 3.9 times more chance to die until 2006. Although the advent of more potent and tolerable drugs, the lack of adherence to the drugs and the high level of adverse effects are still the most important barriers to the prolonged success of the treatment. This study brings relevant information about the durability and efficacy of HAART. However, new studies are encouraged, in special to evaluate ritonavir-boosted PI.A terapia anti-retroviral combinada produz melhora substancial do prognóstico dos portadores da infecção pelo HIV/SIDA. Encontrar o melhor regime para o tratamento antiretroviral inicial é uma das estratégias para aumentar o tempo e a qualidade de vida de PVHA. Foram avaliados 891 pacientes atendidos no CTR-DIP Orestes Diniz com primeiro esquema antiretroviral combinado contendo no mínimo três drogas, iniciado entre 1996 e 2007, através da análise de coorte histórica de portadores da infecção pelo HIV/SIDA. Os pacientes foram acompanhados por 24 meses ou até a suspensão, abandono, substituição do esquema ou óbito. A população era predominantemente do sexo masculino, da cor/raça branca, jovens, solteiros e com baixo grau de escolaridade. Os regimes contendo IP, representaram 61,5% das prescrições. Notou-se diminuição progressiva do uso de IP no regime inicial ao longo do período, correspondendo às modificações nas recomendações vigentes no país. Ao final de seis meses 69% dos pacientes permaneceram em uso do primeiro esquema anti-retroviral combinado, 54% aos 12 meses, 48% aos 18 meses e 39% aos 24 meses. A combinação AZT-3TC e EFV foi o regime mais prescrito e com menor falha (p<0,05). Os regimes contendo ITRNN apresentaram duração e eficácia superiores aos regimes contendo IP (p<0,001). A alta freqüência de regimes sabidamente menos tolerados ou menos eficazes no início do período avaliado, pode ter influenciado no pior desempenho dos regimes contendo IP. A contagem de linfócitos T-CD4+ < 200células/mm3, a dispensação irregular e a ocupação do lar foram fatores de risco para falha e/ou interrupção do tratamento na análise multivariada. O pequeno número de pacientes que possuíam CV anterior ao início da TARC não permitiu a análise de sua correlação com a duração do tratamento. A intolerância/eventos adversos foram o principal motivo para a falha do esquema, seguido pelo abandono/não aderência e pela falha terapêutica virológica Na comparação entre as classes de drogas, notou-se diferença significativa entre os motivos da interrupção da TARC inicial, com maior percentagem de intolerância/eventos adversos para os pacientes em uso de IP e de falha imunológica para os pacientes em uso de ITRNN. Os regimes contendo EFV apresentaram maior duração e eficácia que os regimes contendo NVP. Os pacientes cujo esquema anti-retroviral foi interrompido/ falhou nos primeiros 24 meses de tratamento apresentaram risco 3,9 vezes maior de falecer até 2006. Apesar do surgimento de novas drogas com maior potência e melhor tolerabilidade, a má aderência a medicação e a alta taxa de eventos adversos permanecem como principais barreiras para o sucesso prolongado do tratamento. Este estudo traz informações relevantes sobre a duração e eficácia do primeiro regime anti-retroviral combinado. Entretanto, novos estudos sobre o tema se fazem necessários, em especial, para avaliar os regimes contendo IP reforçados com RTV. Palavras chaves: HIV, SIDA,

Using an international sample, this thesis examines the impact of board CSR orientation, a specific form of board-level governance, on CSR strategy, CSR performance, CSR disclosures, and earnings management. It also examines the impact of CSR strategy on CSR performance and CSR disclosures, a topic that is not yet explored. The findings support the arguments in the literature that board CSR orientation has a positive impact on CSR-related strategy, performance, and disclosures, and it reduces earnings management behaviour. The result also supports the suggestion that CSR strategies are a determinant of having a superior CSR performance and CSR disclosures.

Previous issue date: 2005-04-14Analyze, in patients with primary hyperhidrosis (PH) who was undergone to videothoracoscopic sympathicotomy, the degree of vascular denervation after surgical transection of the thoracic sympathetic chain by measuring ultrasonografic parameters in carotid and vertebral arteries. Methods: Twenty-four patients with PH underwent forty-eight endoscopic thoracic sympathicotomy and were evaluated by duplex eco-doppler measuring systolic peak velocity (SPV), diastolic peak velocity (DPV), pulsatility index (PI) and resistivity index (RI) in bilateral common, internal and external carotids, besides bilateral vertebral arteries. The exams were performed before operations and a month later. Wilcoxon test was used to analyse the differences between the variables before and after the sympatholisis. Results: T3 sympathicotomy segment was the most frequent transection done (95,83%), as only ablation (25%) or in association with T4 (62,50%) or with T2 (8,33%). It was observed increase in RI and PI of the common carotid artery ( p<0,05). The DPV of internal carotid artery decreased in both sides (p<0,05). The SPV and the DPV of the right and left vertebral arteries also increased (p<0,05). Asymmetric findings were observed so that, arteries of the right side were the most frequently affected. Conclusions: Hemodynamic changes in vertebral and carotid arteries were observed after sympathicotomy for PH. SPV was the most often altered parameter, mostly in the right side arteries, meaning significant asymmetric changes in carotid and vertebral vessels. Therefore, the research findings deserve further investigations to observe if they have clinical inferences

Problems related to sustainable development such as environmental issues, human rights, orlabor conditions, are nowadays deeply integrated in our society. It became primordial forcompanies to take into consideration these problems in their business development. For morethan a decade now, car companies started to publish official documents summarizing theircommitments in favor of Corporate Social Responsibility (CSR) actions. Through thesesustainability reports, car producers disclose information concerning their sustainable policyand bring details to stakeholders on performed sustainable actions. Because publication of sustainability reports is a relatively new phenomenon, a lot of studies still have to be made in this sector. In this way, no main studies were made regarding howCSR actions performed and disclosed by car companies evolved in the past decade. Didcompanies keep focusing on the same type of sustainable actions or did some changes occuron the way they conduct their CSR policies? No trends were available to try to understandhow car companies CSR actions evolved. This thesis is an attempt to fulfill this gap and bringa first set of useful findings on this topic. Based on three different car producers which are BMW Group, Ford Motor Company andMitsubishi Motors Corporation, our study analyses these companies 2002, 2006 and 2010sustainability reports and looks at how CSR actions are disclosed. The purpose is firstly todescribe how companies’ CSR commitment disclosure is evolving between 2002 and 2010and secondly to find explanation to the key trends. In order to achieve this, we used six mainCSR categories (Economic, Environment, Human Rights, Labor Practices and Decent Work,Product Responsibility and Society) and classified disclosed information in relation with thesecategories to create trends. For each of these six categories, sub-categories were used in orderto be more precise in the analysis process of the documents. Results showed an important interest of car producers for the environment category whichrepresents, on average, more than 40% of disclosed information in sustainability reports.Society category trend shows an important increase between 2006 and 2010 which led it tobecome the second most represented category in reports. Other categories trends present amore stable evolution with time. As it is explained more in detail in our analysis part, thisattraction toward environmental issues for car producers can be explained by the badreputation given to car producers in terms of emissions, energy consumption and moreglobally environmental protection. Cultural background and business mindset are alsoinfluencing companies’ choices. Responsive behaviors resulting from stakeholder’s pressureas well as adaptation to a weak regulatory framework are additional elements to explain the key disclosure trends.

La seguridad en las personas es un tema común en nuestra sociedad, más aun cuando en los últimos años ha aumentado los robos de vehículos a través del “portonazo” no solo en el barrio alto, sino que en todo el país, afectando a todo tipo de familias. Durante el año 2016 este crimen se ha trasladado a comunas emergentes, dejando inseguros a gran parte de la población que cuenta con uno o más automóviles particulares, un 5,9% de ellos fue víctima de intento de robo o hurto de vehículos durante los últimos doce meses, una cifra no menor considerando el parque automotriz de RM es 1,8M vehículos particulares equivalente a 40% del parque total nacional (fuente INE 2015). El año 2015 las autoridades informaron que entre 4 y 5 autos eran robados cada 1 hora (102 autos por día en Chile) con una tasa de crecimiento de 4,2% respecto del 2014 (fuente Carabineros de Chile – La Tercera). Este alto crecimiento en los robos de vehículos particulares ha generado una industria en este tipo de delincuencia que supera los US $200M anuales, con más de 35.000 vehículos robados anualmente. Sabemos que a nivel mundial, la industria automotriz y la seguridad satelital han diseñados aparatos de rastreo en tiempo real para vehículos de alta gama, para la industria militar y las de uso estándar aplicada fuertemente en flotas. Entendiendo este contexto y dado el crecimiento en robo de vehículos particular, más la alta inseguridad ciudadana instalada, hemos visualizado una oportunidad de negocio para nuestro producto Car Recovery, el que ofrece monitorear y recuperar vehículos robados en tiempo real, a través de seguimiento en línea por un equipo especializado en vigilancia, acompañado de una plataforma robusta de operación 24/7, nuestra ventaja competitiva, es el equipo de rescatistas que acudirán motorizados al recupero del vehículo particular, mientras en paralelo nuestros operadores telefónicos se pondrán en contacto con seguridad ciudadana y Carabineros. Actualmente dimensionamos un mercado potencial superior a los US $310M, pero esta industria no se encuentra desarrollada, tampoco penetrada y tiene un alto potencial de crecimiento en el corto plazo, por ello, determinamos un mercado objetivo de US $50M anuales sólo en la región metropolitana.

Full textAbstract:
This study focuses on the topic of CSR and profitability and extends the current literature on the topic by examining the relationship between CSR and profitability from a game theory setting. Specifically, this study implements game modelling and develops two parts of analysis on the topic of CSR and profitability. The goal of part one analysis is to investigate competing CSR firms in comparison with competing non-CSR firms. The part two analysis is to study a CSR firm and a non-CSR firm that compete in the same market in two scenarios. In scenario 1, the CSR firm and its non-CSR counterpart compete for profitability. In scenario 2, the CSR firm is operating to optimize its defined welfare objective; whereas the non-CSR operates for a maximized profit level. The solutions to the models complemented with a detailed analysis reveal that the CSR could actually gain strategic and competitive advantages over its non-CSR counterpart in both defined scenarios. However, this study does not intend to advocate a positive relationship between CSR and profit performance. The positive relationship is qualified, and whether or not the relationship is positive, as this study shows, is dependent on the firm’s tactics.

Full textAbstract:
The final goal of this document is the construction of multi-band terminal for the CVIS project to allow the communication among cars and between the cars and the roadside infrastructure. For the construction of this multi-band terminal, this document takes as starting point, a new compact disk antenna described in [1]. It consists in a circular patch antenna shorted by a central metallic post. This allows reducing the dimensions of a classical circular patch antenna so it is very useful for our application given that the terminal is going to be place on the top of a car and it should be small enough to be attractive for the final users. Specifically, we are going to analyze the behaviour of this kind of antenna when it radiates in the TM01 mode, because the radiation pattern of this mode is particularly interesting for the applications of the CVIS project. This document is divided into two main parts. In the first one, a study in depth of the behaviour of the antenna proposed in [1] was performed. Firstly, through an analytical model and afterward with the help of two simulation tools (WIPL-D and EMDS), we analyze the influence of the main parameters of the antenna (outer and inner radiuses, height, electrical permittivity and the position of the feed) on its properties (resonant frequency, bandwidth, entrance impedance, the shape of the radiation pattern and so on). A general methodology for the design of this kind of antennas was proposed, and it was put in practice with the design of a prototype for a band around 2 GHz. In addition to the conclusions about the influence of the different parameters of the antenna, another important conclusion was done. It was discovered that the use of the simulation tool WIPL-D Lite was not suitable for the simulation of this kind of antenna. In the second part, this document tackles the construction of a dual-frequency antenna for the bands of 2.4-2.484 GHz and 5.75-5.95 GHz. For this, the present document studies the possibility of stacking two compact circular patch antennas, so we put the one which covers the higher band (the smaller) on the top of the one which covers the lower band (the lager). The two patch antennas have a coaxial feed and the feed of the upper antenna goes inside the central post of the lower antenna to minimize the influence of it on the radiation pattern of the lower antenna. This proposal works out not to be feasible, because we need a lower antenna with a large inner radius to allow the variation of the feed position of the upper antenna in a wide range. This is necessary to get a good matching for the upper antenna. The problem is that the radiation pattern becomes very asymmetric when we increase the inner radius of the patch antenna. To solve that, two alternative were analyzed in this document. The first consists in putting a second feed symmetrically placed with respect to the central post. It leads to a more symmetric radiation pattern so we can choose a larger inner radius. In addition, the introduction of the second feed increases the bandwidth of the antenna. The second alternative is a simplification of the first one. It consists in replacing the upper antenna with a monopole on the top of the lower antenna. It is simpler but it prevents the possibility of stacking other patch antennas to cover more frequency bands in a future. Due to this disadvantage, the first alternative was chosen. Finally, a proposal based on the first alternative, which fulfils quite well all the requirements which were raised in the wording of this master thesis, was presented and studied in depth.

Syfte: Syftet med denna studie är att skapa ökad förståelse för medias roll i förmedlingen av begreppet CSR, corporate social responsibility. Med media menas i studien svensk papperstidning. Metod: Diskursanalys kring CSR i svensk tryckpress, inspirerad av Michael Foucault och Norman Fairclough, applicerad på nyhetsartiklar. I studien används ordet diskurs som en förklaring till att nyhetstexter påverkar den sociala verkligheten. CSR innebär företags sociala ansvar, kring frågor om bland annat miljö, som går utöver vad lagen kräver. Slutsatser: Analysresultatet visar att CSR i nästintill samtliga artiklar benämns synonymt med samhällsansvar, som alltså varit det mest dominerande området som behandlats i de artiklar som har analyserats. Det framkommer även att det finns skillnader i artiklarnas intertextualitet, beroende på vilken tidning de tillhör. När CSR har omskrivits negativt har det varit kopplat till kategorin affärsnytta.

Previous issue date: 2013-08-20Science and Art are two concepts that have been greatly evolved throughout history, mainly due to cultural evolution experienced by humanity itself. Science, in its primitive stage, as synonymous of knowledge, preceded the Arts. However, according to its current concept considered as a result of the proposed method, by Francis Bacon, it is a recent phenomenon when compared to the period of human existence on Earth. Thus, Art preceded Science, because from its beginning it always configured as such, despite the different ways in which it has been presented. This is why the term Arts is used instead of Art. Among the Sciences, separated as Natural Sciences and Humanities, Physics stands out, even in the primitive stage of science, always referred to Nature as a whole, justifying its etymology Physics, the Greek Physis that means Nature and, according to available records, developed with the Arts since prehistory. In this context, this work, which presents a brief history of the evolution of perception and color reproduction by man, has as main attribute a study of the concept of color, pigment and light as taking Physics as a foundation, according to the branch of knowledge called Optics. From a literature search, the author s and other expert s experiences, both in Arts and in Science in General, an approach of Arts and Physics is presented, in terms of interdisciplinarity that exists between the color theme and concepts of physical optics, as one of the branches of this science. Records used are based on works that still exist, such as cave paintings and paintings in other processes, frescoes and sculptures, as well as the bibliography, documents preserved in museums, libraries and cultural venues, and statements from researchers, due to their own works. It was also included in this compilation the development of some technics of color reproduction, both in pictorial art, using pigments, as in architectural lightening projects, fabrication of transparent and colored glasses and at photographic, cinematographic and digital arts from light sources, in its different ways of generation and applications.
Ciência e Arte são dois conceitos que mudaram muito ao longo da história, sobretudo, em decorrência da própria evolução cultural vivida pela humanidade. A Ciência, em seu estágio primitivo, como sinônimo de conhecimento, antecedeu a Arte, todavia, segundo sua concepção atual, em razão da proposta do Método, por Francis Bacon, é algo recente em comparação ao tempo de existência do ser humano na Terra. E, nesse sentido, a Arte antecedeu a Ciência, pois desde o seu princípio ela sempre se configurou como tal, não obstante as várias formas com as quais se apresentou, por isso, por diversas vezes menciona-se Artes ao invés de Arte. No rol das Ciências, agrupadas em Ciências Naturais e Ciências Humanas, destaca-se a Física, que mesmo no estágio primitivo das ciências, referiu-se sempre à Natureza como um todo, justificando sua própria etimologia Física, do Grego, Physis que significa Natureza e, deste modo, de acordo com os registros disponíveis, acompanha as Artes desde a Pré-história. Neste contexto, o presente trabalho, que apresenta um breve histórico da evolução da percepção e da reprodução das cores pelo homem, tem como principal atributo um estudo do conceito de cor, como pigmento e como luz, tendo a Física como alicerce, de acordo com o ramo de conhecimentos denominado Óptica. A partir de uma pesquisa bibliográfica, de experiências do autor e de outros especialistas, tanto nas Artes como nas Ciências em Geral, proporcionou-se uma ampla abordagem das Artes e da Física, em termos da interdisciplinaridade que se verifica entre o tema Cor e os conceitos físicos da Óptica, como um dos ramos desta ciência. Os registros utilizados são fundamentados por obras ainda existentes, desde o tempo das pinturas rupestres até a contemporaneidade, em seus diversos processos, incluindo objetos tridimensionais, como esculturas, dentre outros. Esta fundamentação inclui também a bibliografia, documentos localizados em museus, espaços culturais e bibliotecas, bem como depoimentos de pesquisadores, em função de seus respectivos trabalhos. Contempla-se ainda a evolução de algumas técnicas de reprodução de cores, tanto na Arte Pictórica, com o uso de pigmentos, como na iluminação de ambientes, produção de vidros incolores e coloridos e a Arte Fotográfica, Cinematográfica e Digital, a partir de fontes de luz, em suas diversas formas de obtenção e de algumas aplicações.

Hedén, W. 2016. Kommunikation av CSR. Kulturgeografiska institutionen, Arbetsrapportsserie, Uppsala Universitet The purposes with this paper are firstly to find out how two chosen clothing companies within the high fashion era handle the important CSR (Cooperate Social Responsibility) challenges that today has become a natural part of the clothing industry, and secondly how these companies are communicating their CSR strategy, and then to note any possible differences between their way of doing that. The methods I have chosen to use are by qualitively interviews with the two Fashion companies: Sidenkompaniet and Filippa K. Results from my research shows that both companies have different approaches to the conception of CSR and also uses different strategies how to communicate the CSR message. I found out that Sidenkompaniet, a small company is using the CSR concept as such to communicate their message and strategy. Filippa K though (the larger company), have another approach to CSR. They are not mentioning CSR, instead they want their customer to sense that everything they do is connected to CSR. They want to project CSR as a way of living and that should be felt all trough their business idea from production to the customer without ever mentioning abbreviation CSR. These are the two major different approaches I found during my research.

Full textAbstract:
The standard first aid for a heart attack resulting in cardiopulmonary arrest is effective cardiopulmonary resuscitation (CPR). Chest compressions are most commonly performed on a flat surface with the rescuer kneeling next to the victim with one hand on top of the other on the sternum and elbows straight. This technique of being on the ground may be challenging for those without the mobility and strength to get up and down from the ground. In 2005, the American Heart Association (AHA) Guidelines listed “pedal”, or heel, compression as an acceptable alternative to standard chest compressions (Trenkamp & Perez, 2015). That same year, the recommended depth of a compression increased from 3.8 cm to 5.0 cm (Trenkamp & Perez, 2015). To attain such a depth, extra force and strength arerequired. The heel method may be especially reasonable for those rescuers who cannot attain the floor and those who do not have the cardiovascular or muscular strength to perform traditional chest compressions.
The purpose of this study was to evaluate the effects of performance of hands only (HO) versus the combination (CO) of hands only plus pedal CPR on the electrocardiogram, including heart rate and heart rhythm.
The subjects utilized in this investigation were six men and nine women between 56 and 71 years of age from San Luis Obispo County in California. Subjects underwent two trials with at least a 15 hour rest period in between but no more than one week. Subjects were randomly assigned to either the Combination (CO) trial or the Hands Only (HO) trial. When they came back for their second trial, they did the trial that they did not do the first time.
On average, participants were able to sustain the combination of HO plus pedal CPR longer (9.47 minutes) than they were able to perform standard HO CPR (9.02 minutes) but this difference was not statistically significant (p=0.16). Mean maximum heart rate was 133 ± 23.7 bpm during the CO trial and 125.4 ± 21.9 bpm during the HO trial (p=0.12). Mean percentage of the HR reserve was 75.1% during the CO trial and 61.1% during the HO trial (p=0.09). Mean RPE was not significantly different between CO and HO trials (p=0.2124), nor between genders (p=0.42090). However, for both trials combined the mean RPE was significantly greater at 5 minutes of CPR (4.45 ± 0.53) than at 2 minutes of CPR (3.38 ± 0.31), (p
It may take time for individuals to accept pedal CPR as a viable resuscitation method. With the majority of sudden cardiac arrests occurring in the home among older adults in society, it is important to recognize that pedal CPR is an acceptable method and that a rescuer may have this choice if they either need a break from standard CPR or if they can not attain the ground.

Full textAbstract:
Problemformulering: Denna uppsats avser att besvara/beröra följande frågor:
- Hur tolkar företag begreppet CSR, hur arbetar de med det samt om det finns några skillnader/likheter mellan företagen?
- Hur kommunicerar företagen sitt CSR arbete via olika dokument, finns det några skillnader/likheter mellan företagen?
Syfte: Uppsatsen syftar till att beskriva, förklara och jämföra hur utvalda svenska företag inom konfektionsbranschen kommunicerar kring begreppet CSR mot sin marknad via olika dokument, hur företagen tolkar begreppet CSR samt hur de arbetar med det.
Metod: En fallstudie har genomförts på tre företag inom konfektionsbranschen på den svenska marknaden. Textanalys har genomförts på utvalda dokument såsom respektive företags hemsida, årsredovisningar från 2002 och framåt samt tillgängliga hållbarhetsredovisningar för att se hur företagen kommunicerar kring CSR. Även kvalitativa intervjuer med respektive företag har genomförts för att komplettera textanalysen och för att få ytterligare en synvinkel utöver kommunikation på hur företagen arbetar med CSR.
Teori: De teorier som använts är Carrolls CSR – pyramid samt företags olika ståndpunkter till CSR. Carrolls CSR pyramid tar hänsyn till olika ansvar som måste uppfyllas i CSR arbetet medan den andra teorin tar upp företags olika ståndpunkter till CSR samt hur ståndpunkten kan påverka i vilken utsträckning samt grad man arbetar med CSR.
Slutsats: När det gäller CSR arbetet finns det mer likheter än skillnader mellan företagen. Kommunikationen skiljer sig i omfattning mellan företagen.
